With RemoteScan™ your TWAIN compatible device becomes available to any other computer on your network. Plug your scanner into just one computer, and access that scanner from any other computer on your network, or from around the world through the Internet. Common situations where it useful to be able to share a scanner on a network: A scanner is connected to a computer where someone is working who does not want to stop doing what they are doing so someone else can use the scanner. A scanner is connected to a computer on a home wireless network, and someone on a laptop wants to use the scanner but does not want to have disconnect and then reconnect cables, etc. A higher-end scanner is in a dust-free environment where a technician or other worker physically places the documents and then from their own computers operate the scanner without having to be anywhere near it. At internet cafes and other public use locations where a scanner is located back behind a counter. The counter person can take documents from a customer and place them onto the scanner, then letting the customer operate the scanner from their own computer or work station. This keeps the counter person from having to know how to run any software at all. Go to http://www.remote-scan.com if you need to share a scanner. This is good software!
